Opposite Great Portland Street station.The church was designed 1826-28 by Sir John Soane. Redundant as a church from the 1930s it was used as a book storage facility and then until 2006 it was SPCK offices but has now been converted to an event venue called Number 1 Marylebone with the galleries separated off from the body of the church. The nave area is sometimes used by the evangelical Commonwealth Church.
